While there is nothing quite like the Fashion’s Night Out shopping experience to be found in a bustling bricks-and-mortar store, there are also going to be plenty of ways to shop for good online this year, including the chance for two different people (plus a guest!) to win a trip to New York City for a photo shoot and a tour of the Vogue offices, including a visit to the fabled fashion closet accompanied by one of our editors.

That is because this year, Vogue is collaborating with Polyvore on a brand-new contest, FNO Style Setter, in which readers are asked to create special FNO sets on Polyvore that will be judged not only by Vogue editors like Creative Director Grace Coddington but also by our guest celebrity editors, including Blake LivelyandAlexander Wang.

Intrigued? Here is how it works:

Each Monday at 9 a.m., the theme of the week will be posted on Vogue.com and virtual stylists can go to a special section of Polyvore dedicated to FNO and put together creative sets using at least one item from the limited-edition Fashion’s Night Out collection—and styling it with anything else they find from various FNO online retailers. Every day, our editors pick the set they think best represents the theme and post it with the winner’s name on Vogue.com. On the following Sunday, the celebrity judge of that week will go through Vogue’s seven favorite sets and pick two to be entered into the grand prize.

On September 5, the six finalists will go to a vote cast by the Vogue.com community. The set with the most comments at the end of the voting period will win the grand prize trip to New York. Not creatively inclined? Not to worry. Even if you don’t create a set, you can still win just by commenting on your favorite set. At the end of the voting period—September 9, the day after Fashion’s Night Out in New York—one lucky commenter will be selected at random to also win the same prize—talk about incentive just for participating.

On behalf of everyone at Vogue.com and Polyvore, we look forward to seeing what fabulous things you create.
